Optical characterization of the MP-CDs. A Fluorescence spectrum and B corresponding normalized spectrum. C The maximum PL emission and excitation. D UV–vis spectrum. Inset: photos of MP-CDs under sunlight and UV irradiation. E Time-resolved fluorescence decays of MP-CDs with different doping ratio (Mn:CDs, 1:10, 1:100). The data were collected at an emission peak of 476 nm (λex = 373 nm)
